vb.net associated files?

[thanasis2028]

if vb.net is c#-like ,search for main entry point for your program(in c# its Main()),smth like that.
The trick is-when you doubleclick a file,windows instantly sends this file path to associated application as variable named %1.
If you know where is you app's entry point,=, add a argument to that function-may be smth like Main(eventargs e).
When you find it,put there simple if statement.here's pseudocode:

Code:

if strFilePath != null
  do something with file
else
  open app w/o file

Ok, it was rather different but after a lot of search I found it.
The 2nd parameter of the app is the file opened. So, here is the code:

Code:

'Next code will find if a .mvt was opened
        Dim s() As String = System.Environment.GetCommandLineArgs()'finds parameters and stores it to a string array
        Try
            If InStr(s(1), ".mvt") = s(1).Length - 3 Then  's(1) is the file that was opened
               'open file     'InStr(s(1), ".mvt") = s(1).Length - 3 checks if file has our extension (.mvt)
            End If
        Catch ex As Exception
            '.exe was opened directly and s(1) does not exist
        End Try
